"Ready Kirsten?" asked Tomoko as she gently stroked the girls hip. The obvious puddle the girl was sitting in suggested this was unnecessary to ask but Tomoko wanted to make sure.

Kirsten bit her lip and nodded. "Yes Miss, but can I ask a favour?"

"What would you like Kirsten?"

"Could I…Miss, I want…"

Kirsten looked down and her cheeks began to glow.

"I want to lick your pussy while you cut me Miss. I want to make you cum as you take me apart. I think it'll make me cum too…"

Before Tomoko could catch herself, she leant in and kissed Kirsten firmly. She'd never really been attracted to girls but the kid's earnesty caught her completely off guard.

"I could probably get fired for this" she thought "not that it will matter soon…"

Breaking the kiss, Tomoko beamed. "Of course, Kirsten. I'll just need to be careful."

"Can I help?" asked Ms. Klaassen.

"No thanks, I think I can handle it. Thanks…"

Tatiana sat next to one of the boys who'd been very obediently watching the demonstration despite an huge bulge in his pants and gently guided his hand to her crotch. The boy's surprise at his fingers finding wet, hot naked pussy waiting was only beaten by Ms. Klaassen unzipping the boys pants, extracting his prick and beginning to massage it.

"Sit back Kirsten and we'll get started."

Tomoko gently pushed the girl flat on the steel table before hoisting herself on top, straddling the young girl's face.

"I'll start the same way, with the injection."

Tomoko took the needle but instead of inserting it into a vein in Kirsten's arm she leant forward and slowly slid it into one right next to the girl's almost hairless pussy. Kirsten cooing under her, Tomoko felt the girl's hands grab her hips and pull gently down. The teacher obliged, lowering her cunt into the girl's reach and just as Kirsten found her teacher's clit, Tomoko pushed her thumb onto the syringe's plunger.

"Now - ah! - the incisions…" she paused to look up and saw again the class was paying attention. Commendable. Even Eleanor was paying attention as she rode Bill, clawing at his chest. Bill on the other hand was transfixed at the sight of his cock disappearing into and emerging from Eleanor's cunt above the open, red cavern that was his tummy. By now he had two fingers lodged in his partner's ass and looked to be working on a third.

"Oh well" thought Miss Tomoko, "it's not like he's going to be around to be tested on any of this."

Tomoko cut quickly. As she dug her fingers into Kirsten's tummy, the girl's back arched and she came again, a stream of her cum pattering on the steel table and dripping onto the floor. As Kirsten came, she accidently bit down on Tomoko's delicate lips and the sudden pain sent her over the edge into a mindblowing orgasm.

Tomoko came around and saw blood. Quite a bit of it. In her ecstasy she'd torn at Kirsten's flesh and ripped the flaps of skin back before flopping forward into her student's vicera. A quick check confirmed no real damage had been done and the frantic mouth work and squirming hips of Kirsten meant she was going strong.

Looking up she saw the class agasp, enthralled and insanely turned on. Every boy and girl in the class now had a hand on their, or a neighbour's, sex. Tatiana was almost fisting herself with one hand whilst she worked the fresh cum into the still hard cock of the boy sat next to her, now collapsed into Ms. Klaassen's shoulder. Eleanor, now with three fingers buried in her ass to the knuckles, was coming down from an enormous orgasm and Bill, sporting fresh fingernail scratches on his left pec, had obviously emptied a massive load that was now pooling around the opening of his partner's clasping cunt. Even poor Mr. Porter had finally broken down and was openly stroking his huge cock.

"Sorry everyone, must have gotten carried away." Tomoko jabbed a knee into Kirsten's side and added "Thanks kiddo but go a bit easier now. Eleanor, thank you for taking care of Bill. That will be fine for now."

Eleanor slid off the table and took a seat up front, cum oozing from her pussy, as Tomoko resumed the dissection. Kirsten's organs began filling a steel tray.

"I'll now make an incision in Kirsten's uterus so we can see inside during the next phase of the class." As Tomoko slid two fingers into the subject's pussy she said "You'll probably enjoy this, make sure I do too" and began grinding her hips against the kids face.

"Note how you can see roughly where my fingers are through Kirsten's vaginal wall" Tomoko commented as she slid the fingers up the cervix to stabilise the cut. Kirsten began to buck slightly and Tomoko masterfully made a quick opening in the face of the child's uterus just before she began cumming properly.

"Note - Ah! - The juices flowing up into the uter-AAAHHH!" Tomoko figured the students got the point and allowed herself to join Kirsten.

Mr. Porter helped a very flushed Tomoko off the table and towelled the worst of the blood of her tits and stomach.

"My turn now." he grinned, giving the very top of her pussy the slightest rub with the towel.

"Class, we'll do Mr. Porter and I standing up as we haven't got any more tables."

Mr. Porter leant himself against the wooden desk and braced himself with his arms. His cock stood out a proud 9" and Tomoko pointed out to the class how it bounced slightly with his pulse.

Taking the knife she slid in close to Mr. Porter and whispered…

"Ready Jim? Any requests?"

"Surprise me." he said and chanced a quick peck on Tomoko's cheek.

Tomoko took the syringe and injected its contents into Mr. Porter's arm before quickly grabbing the scalpel. Her back to her class she grinned wickedly at Jim and in one quick cut sliced him from sternum to pubic bone…before the drug had time to work.

It drew exactly the response she hoped, a moan of ecstasy escaped Mr. Porter and his cock leapt at the pain. Dropping to her knees in front of him, Tomoko dug her fingers hard into the cut, slurped the head of his cock into her mouth and pulled. Hard.

With a wet tearing noise Jim's flesh peeled back and his intestines began to fall forward over his cock and Tomoko's breasts. Her eyes went wide as the head of his cock seemed to double in size and she quickly found herself struggling to breathe for the amount of thick cum that had filled her mouth. She pulled her head back and caught spurt after spurt of it on her face, it dribbling down on to her bloody chest and dropping from her perky tits onto the pile of intestines and gore that filled her lap. The sight was incredible and she squeezed her eyes shut, letting it burn into her brain, and came feeling the different sticky messes Jim had made on her face, her tits, in her lap and adding her own as her pussy squirted all over the upturned soles of her feet.

She stood and was able to empty Mr. Porter of anything not needed for today's class before the man was fully aware of his surroundings. Finally he turned and looked at the gore soaked teacher who'd looked so innocent at the start of class.

"Wow…" is all he could manage.

"Wow yourself." thought Tomoko as she noted his still hard cock. "Only me to do now…"

Tomoko reluctantly turned on the sink in the corner of the class room and quickly washed the blood and cum off her. She'd have loved to have left it but it would have made it hard to see where she was cutting. This was going to be hard enough she felt. Her hands were already shaking.

"Ok class, any questions before we go on? I may not be much help from here on but Ms. Klaassen will be taking charge if need be."

She scanned the class, no one raised a hand. But she was pleased to see a good number of notepads with hastily scribbled annotations. Ok…so some had trailed off as the writer came or been smudged by a little semen here and there but overall her last class was doing great. She smiled as a little pride welled inside her.

Hopping up on the opposite end of the bench where Mr. Porter was now slumped in a post-orgasmic daze, Tomoko reached for the syringe of pain blocker and then though against it.

She liked being hurt. Well, she thought she did anyway. She'd cum many a time from sticking pins into her nipples or digging at her clit with the point of a knife. And she remembered little Chrissie who'd practically danced out of her skin when that last orgasm hit her last term…

"Tat…" started Miss Tomoko "if I can't cope, hit me with the drug." Ms. Klaassen smiled knowingly and nodded.

Hands shaking Tomoko picked up the scalpel, signalled for the classes attention and cut.

Her vision went white and Tomoko shrieked, her fingers gouging into the benchtop as her other hand worked the knife.

"CU-CUMMING!" escaped her mouth as she hit the bottom of her incision and started to her left. Somewhere the back of her mind she was aware that Ms Klaassen and several of the girls in the class came along for the ride and she felt a second building fast.

Shifting the scalpel to begin the right incision, she shoved four fingers into her sopping cunt and gouged at that little spot she knew so well with her fingernails. Dragging the knife across the base of her tummy she began to shake uncontrollably as she came.

"Oh god. Miss…" shouted one of the girls as her panties suddenly filled themselves with ooze.

Unknown to Tomoko her shuddering was forcing her intestines out. First a few inches, then a loop a foot or so long, then a cascade that dropped wetly to the floor and began to pool around the teacher's feet.

Ms. Klaassen sat in awe, grinding her knuckles into the underside of cunt. She'd never seen anything like this. She'd supervised this subject every year for nearly a decade and never was it like this. As Ms. Klaassen came she was dimly aware of one of the boys spraying her blouse and left cheek with cum. Normally she'd care. Today she didn't. Not now anyway.

After what felt like an eternity to her, Tomoko blinked her eyes open and surveyed the carnage she'd inflicted on herself. Her intestines were at her feet. Her last cut ended in a ragged lightning bolt of white across her hip bone.

"As you can see class, some women respond very well to pain." Tomoko croaked with a wry little smirk on her face.

"Tommi, that was amazing. You ok?"

"Yes thanks Tatiana. That was incredible…"

With that Tomoko reached inside her ruined tummy and began to slice through the blood vessels and connective tissue that held bits of her together. Bits she wouldn't be needing any more.

"I won't be needing any of it long." she thought as she finished up with a matching incision to the one in Kirsten's uterus "But I'll be needing these for just a little while yet."

Her gaze met Jim Porter's and holding onto it like it was life itself she snarled "Now class, Sex Education."
